Dear Reader:
As I boarded the Cayman Aggressor IV in June, I fretted
  about the trip ahead. How would it compare to my past
  three years of serious Pacific diving in Fiji, Palau, and
  Indonesia? Any Caribbean liveaboard would have a hard act
  to follow. But limitations in money and vacation time mandated
  that I could only dive either the northern Caribbean
  or my local lake. I chose the former, and selected the
  Cayman Aggressor to dive all three Cayman Islands instead
  of being resort-based at one. With the Caymans going
  upscale and becoming less affordable, five daily dives on
  a liveaboard offered the better value.
I was cheered by a delicious barbecue dinner and the
  initial briefing about the boat. Cantankerous Captain Sam
  of past trips was gone, replaced by an amiable Brit named
  Phil, who had previously steered the erstwhile Tahiti
  Aggressor. I had read Chapbook reports about Captain Sam
  making divers change into dry clothes before descending to
  their cabins, but Phil just asked us to conserve water and
  not take deck towels below. The only dark note Phil sounded
  was predicted high winds that might preclude the crossing
  to Bloody Bay Wall.

 Cayman Aggressor IV | 
My first dive at Tarpon Alley on Grand Cayman eased
  my fears about being
  bored with Caribbean
  diving. A small turtle
  swam past as
  soon as I entered
  the clear, 82-degree
  water. I spent most
  of the dive photographing
  an enormous
  school of tarpon
  hanging in heavy
  sheets over coral
  fingers grooved by
  deep sand chutes.
  I also renewed my acquaintance with several species of colorful
Caribbean reef fish.  The crew didn’t object
to my 70-minute dive time and draped me in a
warm towel after I left the hot deck showers.

But ill winds were blowing at our backs.
  The Aggressor couldn’t make the crossing to
  Little Cayman on Sunday as hoped, and the
  seas weren’t looking promising for Monday.
  Captain Phil motored to dive sites near
  George Town for those two days and we made
  the obligatory visit to Stingray City (not my
  type of dive site because I prefer to observe
  wildlife in the wild). The diving at these
  sites was uninspiring, with limited fish and
  lots of dead coral.  
On Wednesday morning, Captain Phil
  announced that not only would we be unable
  to go to Bloody Bay Wall, the first dive was cancelled. One of the generators had
  failed so the boat had to seek repairs at George Town. Phil, fearing mutiny, was
  relieved when we divers only showed polite disappointment, mostly because the diving
  had been poor so far. We learned during the week that other equipment, like the air
  conditioning system, needed major work. The 110-foot boat, built in 1998, was clean,
  attractive and refitted just this year, but it seemed like the company was still
  playing catchup on mechanical maintenance.
After the generator was repaired, the Aggressor motored to the north end, then
  the east end, of Grand Cayman, and the diving improved. We never made it to Little
  Cayman or Cayman Brac. The corals had been badly damaged by Hurricane Ivan so the
  real beauty appeared below 60 feet. There was typically little current and good visibility.
  At Hammerhead Point, the sheer wall was encrusted in branching black coral,
  wire coral and tangled rope sponges. A pair of eagle rays accompanied by a hawksbill
  turtle soared through the blue. The turtle lingered to feast on a barrel sponge
  and pose for photographers. French, gray, and queen angels mingled with triggerfish,
  small Nassau and tiger groupers, puffer fish, scrawled filefish, and juvenile spotted
  drums. Tall sea plumes in the shallower areas harbored slender filefish, while numerous
  flamingo tongues feasted on knobby sea rods. 
Getting back onboard was always easy on the wide ladders. I am 60 years old and
  short but I trotted up the ladders under full gear as easily at the end of my 26th
  dive as my first. Even with a full load of 18 divers, the dive deck felt spacious.  Aluminum 80’s were filled in the dive
  stations to 3,000 psi. I initially set
  up my dive gear, then the crew assisted
  as needed. A covered bench stored
  my mask, light and other gear. I hung
  my wetsuit above my tank and placed my
  fins in a rack on the dive platform.
  With nine photographers on board, the
  three-tiered camera table was full but
  there were plenty of power strips.

Belizean chef Yanis, aided by
  Savio from southern India, served up
  delicious meals and snacks. Continental
  breakfast appeared at 6:30, followed by
  the full cooked meal at 7:00. I made
  inroads into the fresh fruit tray and
  nibbled a bagel or toast before moving
  on to eggs of all styles, omelets, or
  pancakes. Each lunch began with a different
  homemade soup -- I especially enjoyed the corn-and-pepper soup and
a Caribbean version of hot-and-sour.
Deli sandwiches, fajitas, or a medley
of salads and pastas followed. Dinners
were an interesting salad course, followed
by a meat or fish entrée. The
barbecued rib dinner was popular with
the southerners, a tough audience.
My favorite was fish spiced Belizean
style. Fresh, well-prepared veggies
abounded. All my meals were health
spa-suitable had I not eaten the homemade
cheesecake, key lime pie and
bread pudding. Morning snacks were
sweet and afternoon snacks savory -
- banana bread and conch fritters were
standouts. Savio stayed up late to
pour hot cocoa for night divers and
made sure the coffee addicts on board
always had a fresh pot. 
The divers on my trip were loosely
  connected with one dive shop although
  most didn’t know each other, but dining
  tables clustered together in the cozy
  salon made it easy to start bonding.
  Ages ranged from mid-twenties to 60.
  The doctors and lawyers talked about
  their jobs while the rest of us talked
  about diving and food. The crew’s
  celebrity of the week was a gentleman
  who loved ice cream -- no matter what
  the dessert, he wanted ice cream, too.
  By the third night, the crew served him
  cheesecake á la mode without prompting.  
My standard deluxe cabin was quiet
  and comfortable. Big suitcases were
  stored on shore for the week, while my
  small suitcase slid easily under the
  bunk. Two large drawers and a closet
  provided decent storage but because my
  spouse and I could sleep comfortably
  together in the bottom double bunk, we
  also used the upper single bunk for
  storage. Both sides of the bunk had
  reading lights, and we could watch DVDs on our small television. The air-conditioning
  was blissfully not too cold in the cabin or the salon. A plumbing problem on the
  first day was repaired promptly and cleaned up thoroughly. Crew cleaned cabins daily
  and changed the towels. My bathroom was compact -- a curtain separated the toilet
  from the shower -- but adequate, with plenty of hot water and water pressure. 
At Rum Point, I swam over the blue along a sheer wall, watching schools of
  horse-eye jacks, yellow jacks and Creole wrasse well up beneath me. As I topped the
  wall, four eagle rays sailed past, then back again to check me out. A dozen lobsters
  peeked out from crevices, but a brave one scuttled over the coral in broad daylight.
  I also encountered three greater soapfish, a honeycomb cowfish, and a smooth trunkfish
  among other critters. A pair of bridled burrfish started their dance of love as
  I watched.  
The healthiest corals I saw around Grand Cayman were at Babylon. I enjoyed the
  pretty swimthroughs at Trinity Caves but had more fun seeing scorpionfish and other
  fierce-looking creatures at the top. Exploring the expanse of white sand behind the wall, I found yellowhead jawfish, sand tilefish and a myriad of garden eels. At
Round Rock, I encountered a four-foot grouper circled by a pair of midnight parrotfish.
Cleaning stations dotted the surrounding coral where wrasse, Pedersen cleaning
shrimp and banded coral shrimp serviced a variety of fish. I always felt like I was
diving in a giant bath set at a comfortable 82 degrees. Air temperatures reached the
high 80’s at midday but cooled 10 degrees at night.
I spent my surface intervals on the upper deck, sometimes sunning on comfortable
  chaise lounges, other times relaxing at tables in the covered back deck. A wet bar
  area offered Coke, Diet Coke and root beer, as well as Coors and decent Chilean wines for anyone finished with diving for
the day. All beverages were gratis.
The salon held a library of DVDs,
fish ID books and third-rate novels.
Those who opted out of night dives
watched movies in their cabins or
lounged in the hot tub after dinner
with aperitifs. I did all night dives
and enjoyed seeing multiple crabs,
octopi, comet stars, basket stars,
peppermint shrimp, hunting yellow
and southern stingrays, odd snails,
a free-swimming sharptail eel, and
lobsters by the dozen. Some sites
offered better diving after dark than
by day, and some were deeper than
50 feet. Then I too took advantage
of the hot tub, pondering the day’s
worth of dives. 
The dive crew of Jon, Kathy
  and Lowell gave thorough briefings.
  Aided by Captain Phil, they worked
  the dive deck and quickly learned
  the preferences and practices of each
  diver. By the second day, they knew
  who handed up just camera and fins
  and who also handed up weights and
  BCs. Crew carried gear down to the
  dive platform for one woman with back
  problems. Lowell cheerfully served as a dive buddy for an inexperienced single diver.
  No one questioned my dive times and profiles, I just signed back onto the deck with
  my maximum depth and time. Divers could choose to go their own way underwater in
groups of two to four. 
A full array of safety equipment was onboard, and a skiff was always in the water
  when divers were. But at Bonnie’s Arch, I was dropped without warning into a ripping
  current. I kicked valiantly to the edge of the wall, thinking I would drop down
  behind the coral for shelter from the current. Not so. While I glimpsed the arch, the
  view wasn’t worth the effort. Several divers missed their safety stops, feeling it
  was safer to get back onboard. The current’s strength surprised the crew as well, so
  a divemaster went into the water first at the next site to check the current.  
Even some of the less attractive sites rewarded me for my efforts. I saw diamond
  blennies, arrow gobies, and saddled gobies. Giant anemones seethed with tiny banded
  clinging crabs. Arrow crabs and neck crabs teemed over the reefs. And I actually saw
  a ciliated false squilla -- not so dramatic as its Pacific cousins in the same mantis
  shrimp family, but still cool.  
Was the Cayman Aggressor worth its hefty ticket price, plus a $100 fuel surcharge?
  Had we made the crossing to Little Cayman and Cayman Brac, my answer would be
  a resounding yes. Cayman’s North End and East End provide good diving, but a week diving
  only Grand Cayman sites from a liveaboard is disappointing when you’re expecting
  to visit other islands. And not making the crossing to Bloody Bay Wall rankled, especially
  when I learned that the Nekton Rorqual had made the crossing that same week.
  A review of the past year’s Captain’s Logs on the Aggressor Fleet’s website revealed
  that the Cayman Aggressor made the crossing to Bloody Bay Wall on 27 out of 35 cruises.
  The Aggressor Web site says the surcharge is there because most fuel is consumed
  by the generators, regardless of travel distance. Sure, fuel costs are higher, but the
  reasoning seems frivolous. My dive group did not have to pay the fee, but that was
  only because we booked through a dive shop, which had to cajole and threaten the company
into negating the charge. A group of independent divers would have had to pay it. 
Still, it’s always easier to dive from a liveaboard. Land resorts like Little
  Cayman Beach Resort and the Southern Cross Club charge $2,000 to $3,200 for a fullmeal
  plan with only three dives a day. I dove five times a day, followed by night
  dives, with bottom times limited only by deco limits and my own air consumption.
  I paid $100 for unlimited Nitrox fills, while land-based resorts charge $10 to $15
  per tank. Dives were diverse and filled with enough critters to keep everyone, from
  the one newbie on board to old-timers like me, satisfied. The boat has a good crew
  and captain in place, but Aggressor Cruises needs to take care of mechanical issues.
  They should also think twice about that fuel surcharge when they’re not taking divers
  to two out of three destinations they paid to dive at.
